-IMPROVEMNT IN BACK-PD PRESSES.

The Schedule referred to in these Lettera Patent and making parl: of thesame.`

To whom @t may concern:

Beit known th'atI, EDWIN W. HARLOW, of Hastings, ,in the Vcounty ofBarryand State of Michi.

' gan, have invented a new and useful Improvement in a Back-pad Press;and I do declare that the followling is a true and accurate descriptionthereof, refer' ence being had to the accompanying drawing and tov theletters of reference marked thereon and heinga part of thisspecification, in whichgigure l is a perspective view of my device open,an

Figure 2 is a vertical'longitudinal section of the,

same. v l

Like letters indicate like parts in each ligure. The nature of thisinvention relates to an improved press or Vcrimp for forming theAface-leathers of the back-pads in harnesses, and consists in thepecirliar arrangementof a lever with relation to a matrix and die oftheproper form, whereby the greatest power of the former is applied at thepoint where the deepest crimping is`to be done, as more fullyhereinafter set forth.

In the drawing- A represents a metallic plate, having formed there- 'ina matrix, A', of the form and size of the exterior of the face-leatheror cushion ofthe pad.

B is another plate, )having a die, B', on its lower face, which projectsinto the matrix A', whose form it has, but of less size, by thethickness of the leather to he crimped. The die forms the interior ofthe pad. l

Both plates are hinged tog-ether at their rear or shallow ends, as seenat a.

O is a link, one end of 4which is pivoted between a V pair of studs onthe front end of the lower plate'.

D` is a lever, having for its fnlcrum a shaft, b., in-

serted'through' a pair of standards, c, on the fore part of the plate B,with its short arm tnrnednp and hollowed to receive the end of the linkC, while the end of its long arm is formed to enga-gc with a serratedspring-catch, E, rising from the rear end of the plate B. l

The operation of the de vice is as follows:

A piece 'ofrleather of the proper size, and vwell soaked, is introducedbetweenthe opened plates,

which are then closed andthe short arm of the lever hooked into thelink. Y v y The long-arm' of the lever is then forced down until theleather is forced to the bottom of the matrix by `thedie, which is helddown hy the engagement of the lever with the spring-catch until thepad-leather has become set in its shape.

What I claim as my invention, and desire to secure hy Letters Patent,isv -j .The 'construction and arrangement of the matrix and'die-plates AB, links C, lever I), and spring-catch E, as and for the purpose setforth.
